Question

我无法弄清楚为什么这说'＆＃39;错误的synax附近＆gt;＆＃39;

    case changeuserid
    when charindex('toolbar',lower(changeuserid) > 0 then 'TOOLBAR'
    when charindex('mflynn',lower(changeuserid) > 0 then 'MFLYNN'
else (select username from CLAIMSAUDIT_USERS where MC400ID_PHP=changeuserid)    
end AS 'dbusername',

Answer 1

您可以使用以下case格式，由于)

之前缺少>括号，也会出现语法错误

case 
    when charindex('toolbar',lower(changeuserid)) > 0 then 'TOOLBAR'
    when charindex('mflynn',lower(changeuserid) ) > 0 then 'MFLYNN'
    else (select username from CLAIMSAUDIT_USERS where MC400ID_PHP=changeuserid)    
end AS 'dbusername'

Answer 2

您错过了charindex()的结束语。此外，您的case语法不正确。您有一个额外的changeuserid：

(case when charindex('toolbar', lower(changeuserid)) > 0 then 'TOOLBAR'
      when charindex('mflynn', lower(changeuserid)) > 0 then 'MFLYNN'
      else (select username from CLAIMSAUDIT_USERS where MC400ID_PHP = changeuserid)    
 end) AS 'dbusername',

包含CharIndex的Case语句出现问题
